/*
Primitive Data Types
- bool => Boolean
--- Only Two Possible Values [true, false]
--- Value Is Case Sensitive
--- When We Use Boolean Values
------ Anything Has On/Off, Yes/No, True/False
--- Test Boolean In Math
--- Test > And <
--- Test Data [100, 0, -100, ""]
- void => Valueless
--- Without Value
